THE AMERICAN ASTRONOMICAL 

 SOCIETY 



The twentieth meSting of the American Astro- 

 nomical Society was held at Columbia University, 

 on December 26-29, 1916, in connection with the 

 Convocation-week meeting of the American Asso- 

 ciation for the Advancement of Science. The at- 

 tendance was large, forty-nine members being pres- 

 ent, but was unevenly distributed geographically, 

 two thirds of those present coming from the New 

 England and Middle States, and only two from 

 west of the Mississippi. 



By an unusual coincidence, three of the most im- 

 portant com m unications from the standpoint of 

 astronomy were not made at the sessions of the 

 Astronomical Society. Professor Campbell's ad- 

 mirable address on "The Nebulse" was delivered 

 by him as retiring president of the American As- 

 sociation for the Advancement of Science at a 

 general session; and the no less interesting ad- 

 dresses of Professor Brown, on the relations be- 

 tween mathematics and the physical sciences, and 

 of Professor Leuschner, on the determination of 

 orbits, were presented at a joint meeting of the 

 American Mathematical Society, the Mathematical 

 Association of America, the American Astronomical 

 Society and Section A of the A. A. A. S. — which 

 organizations also joined in a very enjoyable din- 

 ner on Thursday evening. As these three addresses 

 will doubtless be published i?i extenso, it is of no 

 use to sximmarize them here. 



At the regular scientific sessions 35 papers were 

 presented, which are here grouped according to 

 their subject matter, rather than the order of pre- 

 sentation. Beginning with the mathematical and 

 instrumental aids to investigation, Hedrick ex- 

 hibited specimens of new tables for rapid inter- 

 polation of logarithmic and other tables, while 

 Schlesinger, discussing the error arising from 

 "neglected decimals," showed that this is usually
